"This final historical scenario is an 18-turn, 200-unit behemoth that is rated 'hard' to boot," reports developer 2x2. "You may as well lose here, but then, the Germans didn't win either. In case you do manage to take Moscow however, there are two further what-if scenarios. There's no point in spoiling this for anybody so just briefly: the what-ifs are challenging and only slightly ahistorical."

Since I may as well lose, it's great that the new DLC includes a pair of Soviet responses to the German attempt on Moscow, both taking place in the deep and bitterly cold winter at the end of 1941 and into early 1942. The finality of this brutal conflict seems appropriate, however, as the developers are calling this the last piece of official DLC for the strategy game.
